The Corn Palace in Mitchell, South Dakota, US, is likely to be replaced within the next 20 years, according to the city's chamber of commerce.
The palace, at around 90 years old, is showing its age and a larger area is needed to maintain Mitchell's history as a tourist destination, according to rapidcityjournal.com.
The original Mitchell Corn Palace was constructed in 1892 and was rebuilt for the third time in 1921. The multipurpose arena is popular for its colourful exterior murals, which are redesigned every year out of corn and other grains.
Mitchell Area Chamber of Commerce president Doug Dailey said the current Corn Palace would be rebuilt after its 100th anniversary.
